I have a problem with my usb modem. I use kppp to connect to the internet,
and after each internet connection I have to disconnect the modem and
reconnect to get it to reset. If i try to reconnect to the internet without
a pulling the plug on the modem, the modem log shows "initializing modem" and
never returns. (Same problem with wvdial except it finally returns with
"Modem not responding")
The system log shows the following when I do the hard reset.
Praire kernel: usb 2-1: USB disconnect, address 6
Praire kernel: ohci_hcd 0000:00:02.1: wakeup
Praire kernel: usb 2-1: new full speed USB device using address 7
Praire kernel: usb 2-1: configuration #2 chosen from 2 choices
Praire kernel: drivers/usb/class/cdc-acm.c: Ignoring extra header

Praire usb.agent[5966]: Keeping default configuration

My /etc/modprobe.conf is:
alias ieee1394-controller ohci1394
alias sound-slot-0 snd-intel8x0
alias usb-controller uhci-hcd
install snd-intel8x0 /sbin/modprobe --first-time --ignore-install snd-intel8x0
&& { /sbin/modprobe snd-pcm-oss; /bin/true; }
install usb-interface /sbin/modprobe ohci-hcd;/sbin/modprobe
uhci-hcd; /sbin/modprobe cdc-acm /sbin/modprobe ehci-hcd; /bin/true
remove snd-intel8x0 /sbin/modprobe -r snd-pcm-oss; /sbin/modprobe --first-time
-r --ignore-remove snd-intel8x0
alias eth0 forcedeth
alias eth1 3c59x
I need to get this solved, as my wife uses this connection over my lan from
her office, and cannot do the reset.
Please let me know if more data would be helpful, or other things I can try.
Thanks
